The HE693STG884 strain gage input module is part of Horner Electric's APG series. This device is structured to support applications with bridged strain gages, commonly found in load cells. The module is equipped with eight channels, ideal for comprehensive measurement applications.
In terms of configuration, it allows input voltage ranges of ±25mV, ±50mV, and ±100mV. The resolution of this unit is notable, featuring a 16-bit precision that equates to 0.8µV, 1.6µV, or 3.2µV depending on the selected range. This contributes significantly to the accuracy of results, rated at ±0.03%. The HE693STG884 also has excitation voltage monitoring set at 10 VDC.
For performance, the module has a high input impedance greater than 1 GΩ, which minimizes the loading effect on the sensors it connects with. It can safely handle maximum input voltage levels of ±100 mV and operates effectively within a maximum safe voltage range of ±35 VDC or AC.
Power consumption is also an essential feature of this module, with a steady-state consumption of 30 mA at 5 VDC and 25 mA at the 24 VDC relay. During inrush, this consumption can peak at 160 mA at 5 VDC and 80 mA at the 24 VDC relay, which should be accounted for in design considerations.
